Here’s a question that was put to me recently about the interaction of Jesus’ divine and human natures:
Question: Since Jesus, as the Son of God and Second Person of the Trinity, is coequal with God the Father (and of course with the Holy Spirit as well) and since God is omniscient, how can the Son not know the timing of the future in Matthew 24:36? “But concerning that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father only.” (ESV)
Answer: The conventional theological explanation is that because Jesus emptied himself of the right to use certain divine attributes (Philippians 2:6ff), he therefore voluntarily put himself in a position where he limited lots of things about his divine nature in order to be truly human.
For example, he was limited to being in one place at a time, he was limited in that he had to eat, sleep, etc. It is natural therefore for him to be limited in knowledge as well, though that seems to have been periodically overridden at times when he had special insight into people’s thinking, etc.
I hope this sheds some light on the issue.
